我正在尝试通过 Vagrant 安装 edx Devstack,我在 Windows 机器上。我收到的错误似乎是由 Windows 不支持的符号链接(symbolic link)引起的。
根据 Dealing with line endings and symlinks under Windows 下的 edx 故障排除指南,我应该在 cygwin 中运行以下命令来处理符号链接(symbolic link)。
git rm --cached -r . && git reset --hard
git config --global alias.add-symlink '!__git_add_symlink(){
dst=$(echo "$2")/../$(echo "$1");
if [ -e "$dst" ]; then
hash=$(echo "$1" | git hash-object -w --stdin);
git update-index --add --cacheinfo 120000 "$hash" "$2";
git checkout -- "$2";
else
echo "ERROR: Target $dst does not exist!";
echo " Not creating invalid symlink.";
fi;
}; __git_add_symlink "$1" "$2"'
git config --global alias.rm-symlink '!__git_rm_symlink(){
git checkout -- "$1"; link=$(echo "$1");
POS=$'\''/'\''; DOS=$'\''\\\\'\'';
doslink=${link//$POS/$DOS};
dest=$(dirname "$link")/$(cat "$link");
dosdest=${dest//$POS/$DOS};
if [ -f "$dest" ]; then
rm -f "$link";
cmd //C mklink //H "$doslink" "$dosdest";
elif [ -d "$dest" ]; then
rm -f "$link";
cmd //C mklink //J "$doslink" "$dosdest";
else
echo "ERROR: Something went wrong when processing $1 . . .";
echo " $dest may not actually exist as a valid target.";
fi;
}; __git_rm_symlink "$1"'
git config --global alias.rm-symlinks '!__git_rm_symlinks(){
for symlink in `git ls-files -s | grep -E "^120000" | cut -f2`;
do
git rm-symlink "$symlink";
git update-index --assume-unchanged "$symlink";
done;
}; __git_rm_symlinks'
git config --global alias.checkout-symlinks '!__git_checkout_symlinks(){
POS=$'\''/'\''; DOS=$'\''\\\\'\'';
for symlink in `git ls-files -s | grep -E "^120000" | cut -f2`;
do
git update-index --no-assume-unchanged "$symlink";
if [ -d "$symlink" ]; then
dossymlink=${symlink//$POS/$DOS};
cmd //C rmdir //S //Q "$dossymlink";
fi;
git checkout -- "$symlink";
echo "Restored git symlink $symlink <<===>> `cat $symlink`";
done;
}; __git_checkout_symlinks'
git rm-symlinks
我还尝试了对 Git symlinks in Windows 的 SO 回答中的命令,产生相同的结果。
输出:
运行上述命令后得到的输出有点奇怪,所以我不确定脚本是否成功。
User@Computer /cygdrive/c/.../Local/devstack/edx-platform/edx-platform $./symlinks-fix.sh
**Git checkout output**

为什么最后会进入Windows风格的命令提示符?这是我不确定 git 命令是否正常工作的地方。
在 Vagrant 中:
运行 vagrant up
和 vagrant ssh
后,运行 paver devstack lms
时出现以下错误(与 paver 的输出类似开发栈工作室
):
vagrant@precise64:~$ sudo su edxapp

据我所知,这是符号链接(symbolic link)的问题(请参阅 this Google 群组上的帖子)。
我是否正确运行了上述符号链接(symbolic link)脚本?如何检查符号链接(symbolic link)是否已成功处理?
其他尝试:
按照google群里的建议(上面的链接),我也做了如下调整:
- 设置 VAGRANT_USE_VBOXFS = true
- 使用提供的 Vagrantfile here
- 设置环境变量 OPENEDX_RELEASE="named-release/cypress"
- 从 Vagrant 实例安装 libxmlsec1。
在多次 vagrant destroy
和 vagrant provision
之后,我仍然有相同的 IOError: [Error 20] Not a directory
问题。任何帮助将不胜感激!
版本:
- Windows 版本:8
- Vagrant 版本:1.7.4
- VirtualBox 版本:5.0.8
- openEdx 版本:named-release/cypress
最佳答案
我认为问题是你的cydrive路径不对造成的。
尝试改变c:\cygwin\etc\fstab
none/cydrive cygdrive binary,posix=0,user 0 0
到
无/cygdrive 二进制,posix=0,用户 0 0
引用:https://cygwin.com/cygwin-ug-net/using.html#cygdrive
更新:
在 CMD 中键入“bash”,然后复制/粘贴脚本的内容
如果你得到相同的结果尝试:
打开 .gitconfig(使用 Notepad++ 或类似工具)并添加此部分(如果尚不存在)
[alias]
add-symlink = "!__git_add_symlink(){\n dst=$(echo \"$2\")/../$(echo \"$1\"); \n if [ -e \"$dst\" ]; then \n hash=$(echo -n \"$1\" | git hash-object -w --stdin); \n git update-index --add --cacheinfo 120000 \"$hash\" \"$2\"; \n git checkout -- \"$2\"; \n else \n echo \"ERROR: Target $dst does not exist!\"; \n echo \" Not creating invalid symlink.\"; \n fi; \n }; __git_add_symlink \"$1\" \"$2\""
rm-symlink = "!__git_rm_symlink(){\n git checkout -- \"$1\"; link=$(echo \"$1\"); \n POS=$'/'; DOS=$'\\\\\\\\'; \n doslink=${link//$POS/$DOS}; \n dest=$(dirname \"$link\")/$(cat \"$link\"); \n dosdest=${dest//$POS/$DOS}; \n if [ -f \"$dest\" ]; then \n rm -f \"$link\"; \n cmd //C mklink //H \"$doslink\" \"$dosdest\"; \n elif [ -d \"$dest\" ]; then \n rm -f \"$link\"; \n cmd //C mklink //J \"$doslink\" \"$dosdest\"; \n else \n echo \"ERROR: Something went wrong when processing $1 . . .\"; \n echo \" $dest may not actually exist as a valid target.\"; \n fi; \n }; __git_rm_symlink \"$1\""
rm-symlinks = "!__git_rm_symlinks(){\n for symlink in `git ls-files -s | grep -E \"^120000\" | cut -f2`; \n do \n git rm-symlink \"$symlink\"; \n git update-index --assume-unchanged \"$symlink\"; \n done; \n }; __git_rm_symlinks"
checkout-symlinks = "!__git_checkout_symlinks(){\n POS=$'/'; DOS=$'\\\\\\\\'; \n for symlink in `git ls-files -s | grep -E \"^120000\" | cut -f2`; \n do \n git update-index --no-assume-unchanged \"$symlink\"; \n if [ -d \"$symlink\" ]; then \n dossymlink=${symlink//$POS/$DOS}; \n cmd //C rmdir //S //Q \"$dossymlink\"; \n fi; \n git checkout -- \"$symlink\"; \n echo \"Restored git symlink $symlink <<===>> `cat $symlink`\"; \n done; \n }; __git_checkout_symlinks"
这将为符号链接(symbolic link)创建一些 git 命令
注意:文件使用 Unix 行尾,请勿使用 Windows 记事本编辑!
然后执行命令
git rm --cached -r .
git reset --hard
git rm-symlinks
我在我的环境中测试过它,它可以工作
